Sleep disorders in critical care unit.

Sleep deprivation is common in critically ill patients in ICU. It is not surprising that sleep disturbances and fatigue are among the most common symptoms in critically ill adults. Many factors such as preexisting sleep disorders, pathophysiology of the underlying illness/injury, therapeutic interventions, medications, and ICU environment, play roles in sleep and fatigue symptoms during recovery from acute illness or injury. Sleep disruption is a significant stressor in the ICU that can negatively affect recovery and even survival.
